Chemical Information
FooDB Nameent-Gallocatechin 3-gallate
DescriptionEnt-gallocatechin 3-gallate, also known as (-)-gallocatechol gallic acid, is a member of the class of compounds known as catechin gallates. Catechin gallates are organic compounds containing a gallate moiety glycosidically linked to a catechin. Ent-gallocatechin 3-gallate is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Ent-gallocatechin 3-gallate can be found in tea, which makes ent-gallocatechin 3-gallate a potential biomarker for the consumption of this food product.
